半导体激光器稳频技术的研究进展

摘要

Semiconductor lasers are widely used in the optical fiber sensing, optical communications and so on. Laser frequency is affected by the surrounding environment, as the communication illuminant frequency floating will waste bandwidth and limits the long distance sensor applications. So the stability of semiconductor laser frequency is very important. This paper compares the various method of instability frequency, discusses the characteristics and development trend.%半导体激光器广泛应用于光纤传感和光纤通信等领域,它的频率受周围环境的影响很大,作为通信光源频率波动会给信道带宽造成很大的浪费,同时限制了长距离传感的应用,因此,半导体激光器的稳频至关重要.对各种稳频的方法进行了比较,讨论了各自的特点和发展趋势.
